Late one night, a multiple homicide occurred at a slaughterhouse in Parthona, a Griffonian city known for its human trade. The wounds were inflicted expertly and by the butchers' implements. Three dead griffons and two dead humans. Parthona police are baffled by the killing for one reason: the killer cut its way out.

Serin, a Parthona detective, is convinced of a suspect. A highly unlikely suspect. Namely, a stupid animal known as a human.

Almata, an earth pony looking for a good human to help her at the farm, snags a good one for a dirt cheap price. Tall, athletic, with a healthy disposition, and it obeys commands well. It looks her in the eyes and stays quiet most of the time, only watching.

The human: always watching. Maybe waiting.

But definitely not killing. That would be ridiculous.
